TY - JOUR A1 - Pfennig, Anja A1 - Wolf, Marcus A1 - Wiegand, Reiner A1 - Kranzmann, Axel A1 - Bork, Claus-Peter T1 - Corrosion fatigue behavior and S-N-curve of X46Cr13 exposed to CCS-environment obtained from laboratory in-situ-experiments T2 - Energy Procedia N2 - In corrosive environments such as CCS bore holes or geothermal power plants the materials loaded cyclically are also exposed constantly to the highly corrosive hot thermal water. The lifetime reduction of (X46Cr13, AISI 420C) is demonstrated in in-situ-laboratory experiments (T=60 °C, geothermal brine: Stuttgart Aquifer flow rate: 9 Nl/h, CO2). S-N plots, micrographic-, phase-, fractographic- and surface analysis were applied to obtain sustainable information on the corrosion fatigue behavior. Maximum number of cycles (here 12.5 x 106 cycles to failure) is reached at σa =173 MPa. No typical fatigue strength exists and passive corrosion fatigue is most likely failure cause.
